I'm interested, but confused (what's new!)
Don't the engineering drawings provide the workmanship standards and specifications for the job - in this example machining?
If you're in a volume production situation, and trying to sort out grey areas like how much flash/burr can remain, you need to come to an agreement with your customer and then include the tolerance on the drawing (I would have thought).
Am I missing something here?
Perhaps more information might help!
